Turn 1

How to beat Waterfall Giant

  • Two timers: Pressure Gun grows by 5 per shot and every move adds 3 to the eruption, so slow decks lose.
  • Killing it is only half the job: you get exactly one full turn before Explode, and need Block equal to the stored stacks, for example 24 if it died right after Siphon on turn four at base values.
  • Weak from Stomp lasts one turn.
  • Siphon heals 10 per player, so co-op gives it more.

Notes

  • 240 HP (250 at Ascension 8+), the Underdocks boss.
  • While it is About to Blow its HP bar shows as infinite and it cannot be killed again; Explode is the only way out.
  • Siphon is hidden from the bestiary.
